I would say they are used equally.

For ptaszek :

Thank you very much, for your kind help,

I have studied "The World Movie History", as a hobby. 

And finally I have chosen "The 522 Best Movies of All Time".  

1) When you use "birkaç" before a noun, you can´t use plural suffix.

Few houses: birkaç ev

Fe students: birkaç öğrenci

etc..

2) We commonly use "kelime" instead of "söz" for "word" noun.

3) If something has got a mistake, we say "hatalı".

You are writing with mistakes in Turkish.

Türkçeyi hatalı yazıyorsun.

Yazmak is a dative verb; that´s why I used "-i" suffix. (y is connection character.

thx. By the way, I didn´t know language names weren´t private, sorry.)
